Assess the nature and extent of bottom sediment contamination
at selected Great Lakes
Areas of Concern (AoCs);

Demonstrate and evaluate the effectiveness of selected
remedial options; and,

Provide guidance on contaminated sediment problems and
remedial alternatives in the AoCs and other locations in the Great
Lakes.

Major findings and recommendations of the ARCS Program
included the following:

Use of an integrated sediment assessment approach,
incorporating chemical analyses, toxicity testing, and benthic
community surveys, is essential to define the magnitude and extent
of sediment contamination at a site;

Risk assessment and modeling activities are valuable
techniques for evaluating the impacts of contaminated sediments;
